I am writing a DXE driver for a paravirtualized HyperV storage device for OvmfPkg. Host hypervisor exposes the presence of this device through ACPI device node in DSDT. Specific AML path itself may be different from host to host but device UID is always a string: "VMBus".
I was hoping to be able to walk DSDT table in my DXE driver to locate this device node and start publishing necessary protocols, but I am having trouble figuring out how to do this, i.e. are there any support libraries or protocols to traverse ACPI tables or how do I have to do that manually. Will be glad for any advice, thanks. _______________________________________________ edk2-devel mailing list [email protected] https://lists.01.org/mailman/listinfo/edk2-devel
